| News | Ryuk Ransomware attack cripples major Newspaper publications in the US

Ryuk ransomware is believed to be the culprit behind the impeded printing & delivery of major newspaper publications in the United States i.e. Los Angeles Times and Tribune Publishing.

Tribune Publications impacted

The malware attack on Tribune Publishing’s software systems was discovered on 28th December 2018. The abuse on the software delayed weekend distribution of the newspaper & affected Tribune publications throughout the country.

 

Among the publications affected include:

Baltimore Sun, Capital Gazette, Chicago Tribune, Hartford Courant, Wall Street Journal,

New York Times, Carroll County Times, Lake County News-Sun, the South Florida Sun Sentinel & Post-Tribune.

 

The Los Angeles Times & San Diego Union-Tribune that were formerly part of Tribune Publishing newspapers were also slammed by the Ransomware.

 

The print editions of the affected newspapers were published on Saturday without obituary section & paid classified ads according to the publications.

 

The attack is believed to have originated outside the US and intended to create chaos & disable infrastructure rather than steal information. The publication further alleges that no subscriber personal details were compromised. Also, it is known that publication’s websites or online editions remained unaffected.

What is Ryuk Ransomware?

Ryuk Ransomware is a descendant of the Hermes Ransomware family that debuted in the month of August 2018. The critical nature of the ransomware, the high ransom demands & the labor intensive nature of the decryption tool makes it popular among the Ransomware family.Ryuk Ransom Note

 

The modular framework of this Ransomware allows criminals to make custom versions against specific targets. Unlike the common Ransomware systematically distributed via massive spam campaigns & exploit kits, Ryuk is used especially for tailored attacks.

 

Ryuk tends to hit high value target that can’t afford major downtime, demanding hefty Bitcoin ransoms.

 

December 2018 brought a new version of this crypto virus that caused disruption in printing & delivery of major newspaper publications in the US.

 

Research reveals that the group behind Ryuk known as Grim Spider has already received nearly 400 Bitcoin that valued more than $1,520,000 from victims in about 4 months. It’s unclear if any of that ransom came from Tribune Publishing.
